Description Lon Hohberger 2007-11-26 16:49:32 EST
For RH clustering the default recovery policy (when no recovery policy is
specified) on RHEL4 cluster is restart - "Restart the service in the node the
service is currently located.".

The desired behavior is to retry a restart on the same node, if that fails again
a failover to another node should be done.

Current default behavior appears endless attempts to restart.

RHEL3 had relocate after X restarts as well as a notion of "false"
starts, which is a special kind of restart.

-- Additional comment from lhh@redhat.com on 2007-11-20 18:06 EST --

Following patch allows a user to set max_restarts="x" and
restart_expire_time="y" in cluster.conf for services and virtual machines.

Basically, restart_expire_time allows one to throttle restarts - that is, if X
restarts occur within Y seconds, relocate the service instead of restarting it.
 Requires recovery_policy="restart" (which is the default).

Also makes the parsing of time values more robust; you can now enter things
like : 1h30m as part of resource metadata or in cluster.conf.
